There shouldn't be any NULL returned form the DB. The data that I'm pulling from the DB into this array (matrix) does contain information (usernames, names, addresses). For some reason it looks like perl is not able to properly identify my $matrix$ab[0] variable (which should be a username). What makes me wonder even more is that it works on one machine but not on the server itself, even though they run the same version of Perl. Could there be any missing modules or something?
